Data Cash

• Data objects in STAR frame work are kept in Data Cash. Methods:

  • StMaker::AddData(TDataSet *ptr) adds produced object into Data Cash;
  • TDataSet *ptr = StMaker::GetDataSet(name); requests object from Cash by name;

• Data Cash in STAR is structured and based on Maker Tree. Search by name is not arbitrary. The strategy is:

• Search data from sub-makers. If not:

• Search data from the same level makers, already processed.

• Search from upper processed makers;

• Etc…

• This allows to resolve name clashes. Maker gets data from the nearest maker sub-tree. It allows to organize the different streams of data with the same name. Makers do not need to account it in code.
